That’s how the states are, but also the stalls tend to have a 1/4 to 1/2 inch (.6-1.25cm) gap at the sides and on the door. So you don’t have much privacy, plus there is often no indicator of weather it’s occupied or not. So you end up awkwardly kinda seeing if someone is in there by checking the gap but also trying not to see what you don’t want to see
Yea, there’s always a latch of some sort.
